Ann: Tuna spawning update March 2010 , page-3

Sydney - Wednesday - March 31: (RWE Australian Business News) -
A clear warning has been issued IMO:

Clean Seas Tuna (ASX:CSS) advised the market on October 19 that it had
set a target of transferring 25,000 Southern Bluefin Tuna fingerlings
into sea cages this season.
The company says this target is unlikely to be achieved but
remains confident it will be able to put fingerlings into sea cages
before the ocean temperatures become too cold, which would be a major
achievement.
Fingerlings that are not transferred to sea cages in April or
May will be transferred to large, on-shore, temperature and light
controlled, broodstock tanks in the new tuna hatchery.
